pplication led .Tune 2S, 1911. Serial No. 635,950.

' Taall whom, it may concer-nr Be' it known that'l, JOHN O. MCKEAN, a Acitizen "of the United States, residing at Westfield int-he county of Hampden and 5 Sta-te of Massachusetts, have invented new and useul Improvements Vin Winding-Machines, of which the following is a specifica-V tion.

My iniention relates tocop winding malo chines of that class which wind conical cops end wherein the cop is driven by contact "with 'av copfdriving drum or. roll. In this typeo winding nif\.c'h i1'1e.IA as heretofore con- 's 'tidetci the cop 'was mounted upon a swingfing 'cop' `:support andfrested upon the cop-V j rivmg drum, said support yielding upward 'as thseop grew in size. This swinging oop supportwas made with a cop holding spindie for rotatably 'supporting the cop tube or shell and this spindle was free to move toward Vand rom'the cop-driving drum with the cop support, and n'some instances was to tilt or rock laterally to allow the cop t itself 'to thecog'drivingdrum. But 26'in all cases thecop as heretofore always been sosupported during' the winding opleration that -it was held pressed against the drum with uniform' pressure throng out its length.

80 My invention has for4 its object to pro' :vide an improved winding machine of the character specified and it consists in pro- Vviding the machine with a cop support which. is n'otz'only movable toward and 85 from the cop-driving rolland constructed so as to permit the co to rock laterally on an axis 'pe `ndicu1ar tangential with rela- -tion to e airis of -t e cop-driving drum so .that the cog is free 'to [it itself to the driving drum, ut which is also constructed so as to hold one end of the cop more forcibly against the' drivin drum than the otherend `.ther"eby causing t 'e cop to be more com- "pactly wound at' that 'end than at the oppofs'ite end. "f I" "*Inthe best'for'xn or invention the oop '@supportis'a'swingin arm comprising two. =mainmembers 'consistgmg of'a hub pivotally` -s'u'p i'ted so as to's'viring` on an axis parallel 'gwit the co #driving drum,and a cop-holdlever w 'ch is pivotally mounted on the u "member so as to turnfon an axis cross- Vwise -ofthealtis of the hub and extending -tangentiall'y with relation to the copdrivi drum and" preferably intersecting the drum 10 fixed to the axis of the cop near the middle of the latter. This cop-carryin lever comprises two arms, one at one s1deof the last-mentioned axis for holdin the 'cop and the other at the opposite side of said axis carrying a so counterbalance weight or the like which yieldingrly holds the cop against and tits it to the driving drum with one end of the cop held more snugly against Said drum than the other.

Other features of myinventionare here inafter pointedout. In the accompanying drawings, Figure 14 is a perspective view of a portion of a cop winding machine embodying one form of my invention; and Figs. 2 land 8 are details hereinafter described.

Havingrefercnces tothe drawings 3 represents the hub member of the cop support of my improved winding machine and 4 they 75 lever cop-carrying member' thereof. The huh 3 is made with a forwardly extending arm 5 provided 'at its ends with a socket 6 within which is swiveled a stud -7 forming part ofthe cop-carrying lever 4. The or- S6 ward end of lever 'l provided withV the usual cop-holding s indle 8 adjustably mounted thereon an adapted 'to hold a conical cop tube or shell 9 against a' driving usual continuously st? driven drum carrying shaft 1l. The hub 3 is rotatably mounted on a rod. or shaft 12 forming a' part of the fra-me of the machine whose axis is parallel with the axis of -the drum 10, while the stud 7 and socket 6 are arranged so that the axis of stud 7 extends crosswise of rod 12 and intersects the axis of the cop-holding spindle 8 about midway between the endso the cop shell or tube 9. The lever 4 has tw arms 4* and 4"; integral with stud 7 and its arm et is disposed at one side of the axis of said stud, while the other arm 4 is disposed at the opposite side thereof and( carries .a counterbalance weight 14 securedv to said arm by a screw 15 so that it 100 Y in the winding which I bviate by the con-` struction described above.

In winding a cop upon my improved machine the counterbalance weight 14 is ad# justed so as to hold that portion of the cop extending from the intersection of the axes of stud 7 and spindle S to the small end of the cop more forcibly against the Vdrivingdrum 10 than the other .end of the cop. At the same time, however, this weight coperates with the weight of the other parts'of the cop support to yieldingly hold the cop as a whole in driving Contact with the drum 10. As a result of the relatively greater pressure at the smaller. end of the cop the convolutions at said smaller end are compactly laid together thereby increasing the..

tendency of the larger end to grow faster than the smaller cud and increase the conicity of the cop. At the same time the cauniform Contact is maintained between the cop and its driving-drum throughout the length of the cop during the winding operation.

The-hub 3 is made with an integral depending arm 16 pivotally connected at 1'( with a forwardly extending rack bar 18 thatrests upon an arm 19 loosely mounted on a rod 2O but connected by lugs 22 with a frame 21 pivotally supported on rod 20.

The bar 18arm 19, rod 20, frame 21 and lugs "3' are parts of the usual stop mot-ion meclianlsm which actsV as usual to pull rack bar 18 forward and thereby swing the cop .support up to liftthe cop oil from the drum 10 and stop the winding'-operation when a thread breaks or the winding operation is finished. During the winding operation the rack bar 18 is, as usual, free to move forward relatively to arm 19 as the cop grows in size.

When the cop is swungnp, either by the stop motion or by hand, 1t is obvious that' the eiect of weight 14 is to throw the point of the cop downward. In order to hold cop between the stops 22 and 23 and arm 5 to provide for free control of the lever '4 by wei ht 14, and to permit the cop to t itself to t e drum during the winding o eration. As herein s own the stops 22. an 23 are lugs on a plate 24 fastened by means'of a screw 25 to the rear of lever 4.

inga cap 6a yielding-ly clamped upon stud 7;

by means of a, screw 26 acting through a.` sprin` 27; By constructing the socket inf this ashion and properly' adjusting screw 26 the socket maybe caused to frictionally grip the stud 7 so as to regulate and control the swinging movements of the cop holding lever 4 on theaxis o'fstud 7.

l. In a winding machine the combination with the driving drum, ot a cop support for yieldingly holding a conical cop against said drum, said support comprising means to provide for lateral rocking movement of* the cop upon Aan axle perpendicularly tangential with relation to the axis of the driving drum, and means for holding one end of'the cop more forcibly against the driving drum than the opposite end.

2. In a winding machine the combination with the driving drum, o a cop support for yieldingly holding a cop against said drum,

said support comprising means to provide for lateral rocking movement of the cop upon an axis passing through the 'cop intermediate its .ends and which is perpendicularly tangential with relation tothe axis of'the driving drum, and means for holding the smaller end of the cop more forcilbly against the driving drum than -the larger end.

In a winding machine thecombination with the driving drum, of a cop support for yieldingly holding a cop against said drum, said support comprising means to provide for lateral rocking movement of the cop upon an axis which intersects the axis of the cop midway between the ends of the latter andwhich is perpendicularly tangential with relation to the axis of the driving drum, and a weight or the like for holding the 'smaller end ot the-cop more forcibly aginst the driving drum than thelarger en 4.
